If you are dealing with a slab that is already in place and there is no vapour barrier below it, there are moisture reduction products you can use that are applied to the top of the slab, such as Planiseal EMB as manufactured by Mapei, which would mitigate the moisture from the slab and would allow you to install your finish flooring over it. This product is and epoxy based product so it should be compatible with the epoxy flooring, but make absolutely sure that they will work together before you install it (check with the manufacturer of the epoxy flooring to make sure the moisture barrier product is ok to use with their epoxy flooring and check with the moisture barrier manufacturer to ensure that it is compatible with epoxy flooring).
Note: this is a two part product, so you need to be very careful in the mixing and application - make sure you apply it within the pot life of the material.
If you have already installed the epoxy over a slab without a vapour barrier below it or without the moisture reduction barrier on top of the slab, there isn't much you can do at that point.
